Description

Technical Field

[0001] The utility model belongs to the technical field of cellulose unloading and discharging devices, and in particular relates to a cellulose unloading and discharging device. Background Art

[0002] In the chemical and pharmaceutical industries, the extraction and processing of cellulose is a complex process involving high temperatures and viscous materials. The challenges are particularly evident in the cellulose filter press unloading stage. During the cellulose filter press unloading stage, the material is usually kept at a high temperature of about 100°C, which can reduce the viscosity of the cellulose and facilitate handling. However, even at this temperature, cellulose still maintains a high viscosity, which places high demands on the design and operation of the unloading equipment. High-viscosity materials tend to accumulate inside the equipment, causing blockage and difficulty in cleaning, increasing the complexity and cost of equipment maintenance.

[0003] Although there are some attempts at mechanized unloading in the market, most manufacturers still use manual unloading. 3 For materials, manual unloading is not only inefficient (it takes about 30 minutes to complete unloading), but also poses a serious threat to the health of operators in a high-temperature working environment. Especially in summer, the high temperature environment may cause heat stress reactions such as heat stroke, which is very detrimental to the health of workers. Utility Model Content

DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0033] In a preferred embodiment, the cellulose unloading and discharging device includes a servo control unit 1, a transmission shaft 2 and a rotary drive unit 3. The transmission shaft 2 is connected to the rotary drive unit 3 and is used to transmit the driving force to the mud knife rake propeller 5. The servo control unit 1 is configured to control the propulsion speed of the mud knife rake propeller 5 to achieve digital quantitative control of the unloading time. In addition, the device also includes a sealing unit 4, which is located between the rotary drive unit 3 and the mud knife rake propeller 5 to prevent material leakage. This configuration allows the discharging device to efficiently and accurately control the transportation of materials under different working environments, while ensuring the sealing performance of the system to prevent leakage of materials during transportation.

[0034] Specifically, the rotary drive unit 3 is connected to the transmission shaft 2 and is configured to drive the transmission shaft 2 to rotate. This action drives the trowel-rake propeller 5 to propel the material. This design enables the entire device to achieve efficient material propulsion through a simple mechanical structure, thereby improving the operating efficiency and reliability of the entire system.

[0035] Specifically, the rotation drive unit 3 is connected to the servo control unit 1 to adjust the rotation speed and direction of the transmission shaft 2 according to the instructions of the control unit. This interconnection design provides a more flexible control method, allowing the servo control unit 1 to accurately control the movement of the transmission shaft 2 according to different operating requirements, thereby improving the adaptability and efficiency of the entire system.

[0036] The connection configuration of the rotary drive unit 3 enables the servo control unit 1 to directly control the motion parameters of the transmission shaft 2, including the speed and rotation direction. This design allows the equipment to more flexibly respond to different working conditions and requirements, and achieve the best unloading effect by adjusting the rotation speed and direction of the transmission shaft 2.

[0037] Specifically, the trowel rake propeller 5 includes a support rod 6, and a wheel hub is provided in the middle of the support rod 6. A center blade 10 is provided at one end of the wheel nut, and a first trowel 8 and a second trowel 9 are distributed on the support rod 6. The design of the trowel rake propeller 5 allows effective cutting and propulsion through the center blade 10 and the first trowel 8 and the second trowel 9 on both sides during the unloading process. This layout not only optimizes the material processing efficiency, but also enables the equipment to adapt to cellulose materials of different types and densities by adjusting the angle and position of the trowel, thereby achieving a wider range of applications.

[0038] Specifically, the sealing part 4 adopts a digital control mode. The digital control mode of the sealing part 4 allows the sealing pressure and position to be accurately adjusted through software, ensuring that a good sealing effect can be maintained under different operating conditions, while preventing damage to the sealing part 4 caused by excessive pressure. This intelligent control technology increases the reliability and maintenance convenience of the equipment.

[0039] The wheel hub 7 is directly connected to the transmission shaft 2. This direct connection provides greater stability and reliability for the transmission system, ensuring the continuous operation capability of the entire drive system under high load conditions.

[0040] As a preferred case, the support rod 6 includes a first part 11 and a second part 12; the first mud knife 8 is arranged in the first part 11, and the second mud knife 9 is arranged in the second part 12, and the first mud knife 8 and the second mud knife 9 have the same structure. The angle between the first mud knife 8 and the support rod 6 is 10° to 80°; the center blade 10 is consistent with the angle of the first mud knife 8 and the second mud knife 9. By accurately designing the angle and position of the mud knife, the efficiency of cutting and pushing can be effectively improved. The segmented design of the support rod 6 allows each part to be adjusted independently to adapt to different operating requirements. This flexible structural design not only enhances the adaptability of the equipment, but also improves the work efficiency and the overall performance of the equipment.

[0041] Specifically, the servo control unit 1 further includes a user interface for receiving unloading parameters input by the user and adjusting the propulsion speed according to the input parameters. In the above scheme, the design of the user interface enables the operator to easily input and adjust unloading parameters, such as unloading speed, time, etc., and the servo control unit 1 adjusts the operating state of the equipment accordingly to achieve personalized operation settings. This optimization of human-computer interaction not only improves the user experience, but also makes the equipment operation more accurate and efficient.

[0042] Working principle: The core working principle of the device is to accurately adjust the speed of the mud blade rake propeller 5 through the servo control unit 1, so as to control the unloading speed and time of cellulose. The servo control unit 1 adjusts the operation of the rotary drive unit 3 by receiving data fed back by the sensor, thereby controlling the rotation speed of the transmission shaft 2. The transmission shaft 2 drives the movement of the mud blade rake propeller 5 by rotation, effectively promoting the unloading of materials. The setting of the sealing part 4 ensures that the material will not leak during the unloading process, keeping the device and the surrounding environment clean and safe. In a further embodiment, the servo control unit 1 includes a visual monitoring system, which allows the operator to monitor the working status of the device throughout the process and adjust the operating parameters in time to optimize the unloading process.

[0043] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
